The design and testing of soil pressure sensors for in-field agricultural and forestry traffic.
(2005)River stage or flow rates are required for the design and evaluation of hydraulic structures. Most river reaches are ungauged and a methodology is needed to estimate the stages, or rates of flow, at specific locations in ... -
Design of a brush cutter blade and its integration into a semi mechanized sugarcane harvesting system.
(2007)Sugarcane is an important crop for South Africa. It provides employment and valuable foreign -
The design, construction and testing of a mobile essential oil distillation unit.
(2005)Steam distillation is the most widely accepted process for the large scale production of volatile essential oils from herbaceous material and is also regarded as the standard practice throughout the flavour and fragrance ... -
Detection of changes in temperature and streamflow parameters over Southern Africa.
(2005)It has become accepted that long-term global mean temperatures have increased over the twentieth century. However, whether or not climate change can be detected at a local or regional scale is still questionable. The ... -
Determining the capability of a vegetation cover to limit effluent leaching from a waste impoundment.
(2009)A final cover on a waste impoundment is the main physical barrier between the waste impoundment and the environment designed to protect against physical, chemical and biological factors isolating the waste from the atmospheric ... -
Developing a method to estimate the water use of South African natural vegetation using remote sensing.
(2016)The scarcity of water is a growing concern throughout the world. It is essential to accurately determine the quantity and quality of this valuable resource to aid in water resource planning and management. For this purpose ... -
Developing a real time hydraulic model and a decision support tool for the operation of the Orange River.
(2002)This thesis describes the development of a decision support tool to be used in the operation of Vanderkloof Dam on the Orange River so that the supply of water to the lower Orange River can be optimised. The decision support ... -
The development and assessment of a prototype water accounting system for South Africa using the ACRU2000 and MIKE BASIN models..
(2010)South African water management areas could find themselves without enough water for its users due to new methods of performing water allocation as stipulated in the National Water Act of 1998. A water accounting system ... -
Development and assessment of an automatic short furrow irrigation system.
(2010)Automated short furrow irrigation (ASFI) is a prototype irrigation system that has the potential to be robust and relatively low-cost, with highly effective and efficient water use. ASFI has low energy requirements because ... -
Development and assessment of rules to parameterise the ACRU model for design flood estimation.
(2015)Design Flood Estimation (DFE) is essential in the planning and design of hydraulic structures. Recent flooding in the country has highlighted the need to review the techniques used to estimate design floods in South Africa, ... -
The development and assessment of techniques for daily rainfall disaggregation in South Africa.
(2005)The temporal distribution of rainfall , viz. the distribution of rainfall intensity during a storm, is an important factor affecting the timing and magnitude of peak flow from a catchment and hence the flood-generating ... -
Development and evaluation of a sugarcane yield forecasting system.
(2000)There is a need in the South African sugar industry to investigate improved techniques for forecasting seasonal sugarcane yields. An accurate and timely forecast of seasonal cane yield is of great value to the industry, ... -
The development and evaluation of an operating rule framework for the ACRU agrohydrological modelling system.
(2001)Dams hold numerous benefits for society through their ability to store water on a long-term basis. However, it is well-known that there is a detrimental effect of dams on the rivers that they impound, and this has been ... -
Development and evaluation of techniques for estimating short duration design rainfall in South Africa.
(1998)The objective of the study was to update and improve the reliability and accuracy of short duration (s 24 h) design rainfall values for South Africa. These were to be based on digitised rainfall data whereas previous ... -
Development of a climatic soybean rust model and forecasting framework.
(2009)Soybean rust (SBR), caused by the fungus Phakopsora pachyrhizi Syd., is a real threat to soybean crops in South Africa. Its ability to spread rapidly and its potential to severely reduce yields have earned it the reputation ... -
Development of a connectivity index to assess aquatic macroinvertebrate species vulnerability to thermal change : a case study in KwaZulu-Natal Province.
(2015)Connectivity of river systems is a critical ecological component affecting not only the integrity of aquatic systems but also freshwater species’ habitat, community structure, migration and other life activities such as ... -
Development of a geographic data model for hydrological modelling.
(2006)Hydrology is a multi-disciplinary science, and therefore derives data from diverse sources, with the data often of a spatio-temporal nature. A recent trend has been to combine these data with GIS, due to the data’s geographic ... -
Development of a spatial sugarcane transport infrastructure-planning model.
(2008)Due to the significant cost of transport in the sugar industry, a model, named FastTrack, was developed to investigate infrastructure planning opportunities. The model mathematically incorporates road construction and ... -
Development of techniques for the assessment of climate change impacts on estuaries : a hydrological perspective.
(2012)Global climate change is a naturally occurring phenomenon, influencing weather and climate patterns. However, the greatest cause for concern at present is the rate at which climate change is currently occurring. Natural ... -
A distributed sediment delivery ratio concept for sediment yield modelling.
(2004)Identifying areas of the hillslope that are most sensitive to soil erosion and contribute significantly to sediment yield is a primary concern in environmental protection and conservation. Therefore the ability to predict ...
